BP p.l.c. is a British multinational oil and gas company headquartered in London, England. It is one of the oil and gas "supermajors" and one of the world's largest companies measured by revenues and profits. It is a vertically integrated company operating in all areas of the oil and gas industry, including exploration and extraction, refining, distribution and marketing, power generation, and trading. BP's origins date back to the founding of the Anglo-Persian Oil Company in 1909, established as a subsidiary of Burmah Oil Company to exploit oil discoveries in Iran. In 1935, it became the Anglo-Iranian Oil Company and in 1954, adopted the name British Petroleum. BP acquired majority control of Standard Oil of Ohio in 1978. Formerly majority state-owned, the British government privatised the company in stages between 1979 and 1987. BP merged with Amoco in 1998, becoming BP Amoco p.l.c., and acquired ARCO, Burmah Castrol and Aral AG shortly thereafter. The company's name was shortened to BP p.l.c. in 2001. Wikipedia
